My array is [berlin, london, paris] how do I replace paris with new york?

You need to address it by index:
arr[2] = "new york";
Since you say you don't know the position, you can use Array.IndexOf to find it:
arr[Array.IndexOf(arr, "paris")] = "new york"; // ignoring error handling
You could also do it like this:
arr = arr.Select(s => s.Replace("paris", "new york")).ToArray();

This solution is quite dangerous. If you have similar strings they will be changed. For example you have: "York","Paris","New York",... If you want change "York" with "Berlin" you will have then: "Berlin","Paris","New Berlin",...
